The original recipe for Coca-Cola isn't patented, and is one of the most guarded secrets within the food industry. That is, until This American Life was surprised to find it in a 1979 newspaper. The internet is abuzz with the story, though Coca-Cola just denied that this is in fact the real recipe.
